algorithm where the window size at the start of slow start phase is 1 MSS and the
threshold at the start is 1st transmission is 16 MSS. Assume TCP use over a lossy
link i.e., timeout occur after transmission of 7th packet . What is the congestion
window size at the end of 14 RTT (in MSS)?

I got this question the answer is 11

at loss of 7 packet the cnwd size is 18 MSS time out occurs therefore threshold reduce to 9 and cnwd starts from  and now exponentially grow till 9  then till 11 u will get 14 th packet therefore CNWD will be 11MSS
